Filament Clip for 1.75mm

I thought of a new design for filament clips, as the ones I have been using don't seem to stop the filament from getting tangled very well, and also are hard to find sometimes. This one won't let the filament wrap around, and it's hard to miss. Also: branded, because ;-)Let me know if you're interested in a 3mm version.

Assorted Filament Clips (1.75 mm)

Each clip is designed to fit each unique brand of spool. It was designed for a .3 mm nozzle. It makes two perimeters with no fill. It may work with a 0.4 mm nozzle but I have not tried it yet. These are for 1.75 mm filament.Hatchbox clip: shown on red filament spoolMaker Geeks clip: shown on green filament spoolUltimaker clip: shown on black filament spool
